And Jamie, what's your opinion of a thick copper headgasket set? How do we think they seal when compared to a set of factory head gaskets? I noticed this post in your top-end rebuild thread:
I remember reading about a guy with a supercharged Hilux that was using extra thick copper headgaskets (around 3mm or .112" IIRC) in an effort to reduce compression because he was having ping issues. Since I'm supercharged anyway, I might be interested in going a similar route and make up for the reduced compression with increased boost...Originally Posted by MTL_4Runner
